Vedclass · Answer

(B) The reaction of silica $(SiO_2)$ with hydrogen fluoride $(HF)$ proceeds in two steps.First,silica reacts with $HF$ to form silicon tetrafluoride:$SiO_2 + 4 HF \rightarrow SiF_4 + 2 H_2O$Then,the $SiF_4$ formed reacts further with excess $HF$ to produce hexafluorosilicic acid:$SiF_4 + 2 HF \rightarrow H_2SiF_6$Thus,the final product is $H_2SiF_6$.
